Behavior Genetics
|
the study of the relative power and limits of genetic and enviornmental influences on behaviors
|
|
|
Nature
|
Dictates what could be
DNA, genes, gene expression (things you are born with and inherit that could be developed but arent always |
|
|
Nurture
|
Dictates what is
enviornmental influences (mostly things that are developed) Nurture is influenced by parents, peers, culture |
|
|
Heritability
|
The extent to which variation among individuals can be attributed to thier differing genes
|
|
|
Reproductive Advantage
|
Traits that have reproductive advantages prevail over time (survival of the fittest).
Sometimes come from mutations |
|
|
Mutations
|
A random error in gene replication. Introduces diversity into the gene pool. Adaptive mutations are passed on to offspring. Maladaptie mutations are not passed on. Neutral mutations may or may not be passed on to offspring
|
|
|
Selection Pressures
|
Females and males face different pressures when it comes to human sexuality
|
|
|
Mating Strategy
(females) |

|
|
|
Mating Strategy
(male) |
Generally males have more of a choice because they are not invested in reproduction. In shorterm strategies, only attraction is important. In long term strategies, attraction, health, good parent and fertility are important
|
|
|
Evolutionary Psychology
|
Asks why humans are so alike. Study of the human mind and behavior shaped by the pressures of natural selection
|
|
|
Post-hoc rationalization of behavior
|
Starts with the result and then form theory. Works backwards to form an explanation
|
|
|
Hindsight Explanation
|
when you explain a theory based on the results.
|
|
|
Other critiques of evolutionary psychology
|
no reasonable method to empirically test the evolutionary "theory"
provides justifications for promiscuity, rape, abuse and murder |
|
|
Biopsychosocial approach
|
book
|
|
|
Twin studies
|
examines twin reared apart and compares them to twins reared together. Found that monos have similiar personalities, abilities, attitudes, interests and fears. Monos are more similiar thatn dizygotic.
|
|
|
Monozygotic
|
Identical twins, same genetic makeup
|
|
|
Dizygotic
|
Fraternal twins
|
|
|
Adoption Studies
|
examines adoptees, their adpotive parents and their biological parents. Found that enviornment has no effect on PERSONALITY but it does effect attitudes, values, manners, faith, and politics
|
|
|
Strong Situation
|
Situation that causes one to behave in a certain way
EX innovative free spirit can not act/be like oneself/one's personality in the army |
|
|

|
Assumes tht children learn gender-linked behaviors by observing and imitation and by being rewarded or punished
|
